Line up both rails with the bolt (already installed) and the hole (pre-drilled) an insert the bolt.

Put spacer (black plastic) on (rounded side facing the bolt entry) and put on nut (using the rail-bolt wrench makes it easier; see instructions written with rail-bolt set).

Use rail-bolt wrench to tighten nut. If you're using glue, put the glue on the ends before tightening.

Since the plug is on the bottom, the finale result looks great!
